Abstract
Disclosed herein is a fusing device. The fusing device includes a first heating source including a first heater and a first conductor connected to the first heater, a second heating source including a second heater and a second conductor connected to the second heater, a fusing member heated by at least one of the first heating source and the second heating source. The fusing device includes a pressing member disposed to face the fusing member to press a printing medium toward the fusing member, where the first heating source includes a first non-heater portion in which the first heater or the first conductor is sealed so that a part of the first heating source does not generate heat.
Claims20
A fusing device comprising:
- a first heating source including a first heater and a first conductor connected to the first heater;
- a second heating source including a second heater and a second conductor connected to the second heater;
- a fusing member to be heated by one or more of the first heating source and the second heating source;
- and
- a pressing member disposed to face the fusing member to press a printing medium toward the fusing member,
- wherein the first heating source includes a non-heater portion configured to block heat generated from a part of the first heating source in which a portion of the first heater or a portion of the first conductor are sealed.
An image forming apparatus comprising:
- a fusing device configured to fuse a visible image transferable to a printing medium;
- the fusing device including:
- a first heating source including a first heater, a body having the first heater disposed therein, the body formed to extend in a width direction of the printing medium, and a first conductor connected to the first heater;
- a second heating source including a second heater, a second conductor connected to the second heater, the second heater being formed to be longer than the first heater so that a second heating section is greater than a first heating section of the first heater and includes the first heating section;
- a fusing member to be heated by one or more of the first heating source and the second heating source;
- and
- a pressing member disposed to face the fusing member, the pressing member being configured to press the printing medium toward the fusing member,
- wherein the body includes:
- a hollow;
- a heater portion including a gas in the hollow;
- and
- a non-heater portion to block the first heater or the first conductor from the gas in which the first heater or the first conductor is sealed.
A fusing device, comprising:
- a fusing member configured to fuse a visible image to a printing medium;
- a pressing member disposed to face the fusing member, the pressing member being configured to press the printing medium toward the fusing member;
- a first halogen lamp including a halogen gas and a first heater extending in a width direction of the printing medium to heat the fusing member, the first heater being provided with a non-heater portion in which a part of the first heater is sealed to be blocked from heat from the halogen gas;
- and
- a second halogen lamp provided with a second heater extending in the width direction of the printing medium to heat the fusing member.
